Also you can find my post in the Fiji forum on couchsurfing.org
I'll just reply here for now...
Vegetarian no problem, we usually are anyways unless we catch
fish and then we can cook it separate.
If you need to fly out of
Vanuatu or wherever we are that will be fine. I'm not sure if I will go all the way to Hawaii either, but I know of a great job on the Big Island. Where are your cousins?
As far as
sea sickness most people get over it after a few days, from my experience. Some don't though and there's only one way to find out. It won't be too rough for long on the first short crossings and then you'll know before the big crossing to Hawaii.
What state(s) are you from?
Nepal is next on my list after
Asia.
Based on what you've said already I would say you're welcome onboard if you want to be!
But we can connect on FB or voice first too...
